Heretics of Silver City

I, Lu Chen, have a PhD in quantum physics and the youngest nominee for the Nobel Prize. Once he traveled through time, he became the only "demon-free person" in the magical world. Others ridiculed me as a waste who could not communicate with the elements, and the church declared me a heretic who was not tolerated by God. It doesn't matter. While others were practicing magic, I wrote the "Mathematical Principles of Natural Philosophy" of this world. While the mages chanted spells, I created a "railgun" that did not require magic power. While they were still praying for the gods to descend, I had already started writing the programming code for "Twilight of the Gods". The church finally panicked and asked me, "What exactly do you want to do?" I adjusted my non-existent glasses and said calmly: "Don't be nervous, I just want to bring a little bit of scientific rationality to the world." "By the way, prove it to those superior gods——" "You are not invincible."
